This invention relates to a roofing element and more particularly to areversible shingle of the interlocking type.

It is an object of my invention to provide means I integral with theshingle body whereby the lower exposed edge of the exposed lap portionmay be securely locked down, regardless* of which edge of the shingle isexposed to the weather.

It is a further object of my invention to provide a shingle elementcapable of being reversed in laying yet which cooperates with adjacentshingles to provide a continuous connected lower edge' in each course ofshingles whereby the edge portions are prevented from warping or beingblown upwardly, the appearance and eiliciency ot the roof beingconsequently maintained against the elements.

Other objects and advantages of my invention will appear from thefollowing detailed description in which j j Fig. 1 is a plan view of apreferred embodiment of my improved type of shingle;

Fig. 2 illustrates a method of cutting the shingle of Fig. l whereby theshingle may be cut from a single web of material without waste; and

Fig. 3 illustrates a fragment of roof laid with the shingles ofqmyinvention.

InFig. 1 wherein a preferred embodiment of my invention is shown,reference numeral 21 indicates a main body. portion ofy'a shingle 20 ofgeneralquadrilateral shape, the body of the, shingle being dened bylongitudinal edges 22 and 23 and by sides24 and 25; It will be notedthat the sides 24 and 25 are of substantially equal lengths, whereaslongitudinal edge 23 is of som- I what greater length than longitudinaledge 22.

` projection 35, and a rec At the intersection of side 25 and edge 23, aprojecting key portion 26 is provided, the lower side of which lies inalinement with and constitutes an extension of edge 23. The side edge ofkey 26 extends vertically on a line parallel to the side 25 to a pointof intersection with an oblique upper edge 28, the two intersecting toform a pointed projection 27. 'I'he side 25 extends vertically from theline 28 to form with an oblique line 29, a second projection 31 which issimilar in shape to the -projection 27. The line 29 runs inwardly towardthe body portion 21 oi the shingle 20 to the line 32, which rises alonga vertical plane to the longitudinal edge 22, lines 29 and 32 thusdeflning a recess 46.

In a similar manner a key 33, projection 34, 47 are formed adjacent theside 24. i

The longitudinal side 23 is provided adjacent (Cl. 10S-7),

the key portions 26 and 33 with slits or slots 36 and 37, respectively.Slits 38and 39 in alinement with slits 36 and 37, respectively, areprovided in the` upper edge 22 adjacent the respective projections 31and 35. In Fig. 3 I have shown by way of illustration a section of aroof laid with my improved type' of shingle. The several courses of theshingles shown in the roof, i. e., courses I, II and III,- are shown asbeing laid by separate methods to 10 more fully describe the variousmethods of application to which the shingle of the present invention isadapted. l

In course I, which illustrates my preferred method of laying, theshingle units are laid l5 in adjacent overlapping relation with thelongitudinal edges 22 and 23 placed in alinement one` with another andwith the longitudinal edges 23 forming the lower exposed edge of thecourse. The projections 27 and 34 of one shingle are 20 locked in theslits 36 and 37 of the adjacent shingles to form a continuous lower edgewhich is securely locked in place. It will be noted that with respect tocourse I, either shingle may overlap the other so that the position ofthe transverse edge of the overlapping shingle varies, Ydepending uponwhich of a pair of adjacent shingles over.- laps the other. Hence,theshingles may be arrangedto avoid a monotonous design.

In course II, the method of laying comprises a I lacing of the keyportions 26/and 33 and the projections 27 and 34 with the slits 36 and37 of adjacent shingles, thep'rojectio'n 27 of one shinglea being lockedin the slit 37 oi the adjacent shingle, and the projection 34 of theadjacent shingle be- 35 ing locked in the slit 36 of the rst shingle.This lacing of the joint between adjacent shingles provides' a secureand rigid connection between the adjacent shingles which serves to holdthe lower edge of the course down against the roof, 40 therebypreventing warping and consequent leaking by the action of the elements.

In course III, I have shown still a further method by which my shinglemay be laid. While the adjacent shingles are laid in adjacentoverlapping relation as in courses I and II, the relatively shortlongitudinal edge 22 of one shingle is alined with the relatively longerlongitudinal edge 23 of the adjacent shingle, the alternate relationbeing continued throughout the course. Considering y two shingles a andb in course III, shingle a. is

laid with the longitudinaledge 23 at the top and longitudinal edge 22 atthe bottom, whereas shingle b is laid with the longitudinal edge 22 atthe top and the longitudinal edge 23 at the bot- 555 tom. Shingle b islaid to overlap shingle a, the shingles being locked adjacent both thetop and bottom edges. At the top joint the projection 34a is passedunder projection 35D and locked in slit 39h. At the bottom joint, theprojection 34b locks directly with the slit 39B. Thus the adjacentshingles of the course are. formed in a continuous strip, the individualmembers of which are joined at both the top and the bottom edges of thestrip.

While I have shown a roof composed of courses laid by diierent methods,it is to be understood that this showing is purely by way ofillustration and in practice a roof could be laid with only one methodof laying employed throughout or a combination of methods as desired.

The shingles of my invention may be composed of various materials, butthey are preferably constructed from a felt or brous base saturated withbituminous material to render it waterproof, coated with a bituminous orasphalt composition and subsequently surfaced with granular material.The brous base is preferably manufactured in the shape of a long,continuous web 41, shown in Fig. 2 having parallel sides as indicated.

In order that the shingle of my invention may be cut from the web 41without waste, a method of cutting as shown in Fig. 2 is preferablyfollowed. Four shingles are formed at one time transversely o f the web,although it is to be understood that any desired number may be formed,according to the relative dimensions of the web and of the shingles. Theweb 41 is cut transversely on lines 42, which are interrupted by thecuts forming truncated triangular sections 43 alternately positioned onopposite sides of the lines 42. It will be noted that the offsetsections 43 at the ends of the web are of one-half the size of theinterior sections 43. The web is slitted or slotted at 44 to form aseries of transversely alined slits or slots at spaced intervalslongitudinally of the web. Two series of slits 44 are provided to eachtransverse cut 42. The web is subsequently severed on longitudinal lines45' to provide the shingle units desired. It will be noted that by themethod of cutting disclosed, the slits 36, 37, 38 and 39 of the shingles20 are formed in transverse alinement and in adjacent relation so thatone cut serves to slit two shingle units. It will also be noted that therecesses 46 and 47 are complemental in size and shape to the projections26,

27 and 33, 34 of adjacent shingles, thereby eliminating waste ofmaterial in cutting since the .ly with material ofone color and partlywith material of a second color, thus producing a pleasing, vari-coloredeffect when laid.

From the above detailed description, it is obvious that my invention ispossessed of many advantages.

A reversible shingle is provided which isv capable of being laid by anumber of methods, a securely lapped lower edge being obtained by eachmethod.

The structure of the shingle, including the projectionsat the oppositecorners of one edge and the two pairs of slits in the opposite edges,one pair being located adjacent the projections, provide a shingle whichmay be laid either in normal adjacent relation or in alternate reversedrelation to obtain any desired color effect or the like, while providinga locked lower edge which is securely held down and protected fromwarping and consequent action of the elements. Where the shingles arelaid in alternate reversed relation, they are locked at both the upperand lower edges with a tight joint, thereby providing a strong and rigidunitary structure possessed of highly weather resistant properties.
